ABSTRACT
Cystic echinococcosis (CE) is a zoonosis caused by Echinococcus granulosus. It is difficult to diagnose CE by clinical symptoms alone, therefore, radiological and serological examinations should be conducted as well. The aims of this retrospective study were to evaluate the biochemical, hemogram, serological and radiological findings of patients prediagnosed as CE, and to survey epidemiological data to detect the status of the disease in our region. A total of 253 patients (148 female, 105 male) who were admitted to Hitit University Training and Research Hospital in Corum province (located in the central Black Sea Region of Turkey), between October 2009 to July 2013, were included in the study. Serum samples collected from the patients were analyzed by indirect hemagglutination (IHA) test, in the Microbiology Reference Laboratories of the Turkish Public Health Institute, and 1/160 and higher titers were considered positive. Twenty-three (15.5%) of female patients and nine (8.6%) of male patients, with a total of 32 (12.7%) were found to be seropositive. The difference between the gender was not statistically significant (X2= 2.72). The age range of the 32 seropositive patients was between 16-90 years (mean: 51), and of them 24 (75%) being over 40 years old was found as statistically significant (X2= 22.45). All of the seropositive patients presented radiological findings diagnosed with ultrasonography and computed tomography. Additionally, it was noticed that two patients (one male, one female) who were seronegative by IHA test, have passed a CE operation and the diagnosis was confirmed with pathological findings. Of the patients 43.8% were admitted to general surgery, followed by infectious diseases (21.9%), gastroenterology (21.9%) and other (12.5%) clinics. Radiological diagnosis showed that 31 (96.9%) of seropositive patients had CE in the liver, of them two (6.3%) also had lung involvement, while one patient (3.1%) had intraperitoneal involvement alone, without liver infection. Although 50% (16/32) of patients resided in Çorum urban area, most of them were dealing with agriculture and animal breeding. Among the biochemical parameters, GGT were detected with highest level (28%), followed by ALT (16%), AST (16%) and ALP (13%), while the other parameters were normal. Elevated RDW level was the most frequently observed result (29%) among hemogram parameters, while decreased levels of hematocrit, hemoglobin and MCV were detected in 23%, 19% and 19% of the patients, respectively. Eosinophilia was detected in 19% of the patients. In conclusion, for the diagnosis of CE, which is still an important public health problem in our region, a comprehensive evaluation of clinical, radiological, serological and biochemical findings is needed, to avoid a confusion of other diseases with similar clinical symptoms.
